I had to do something about my current shock setup. I was running the toxic drop shocks. These things are way too stiff for any track use. I did a search and watched lotsoffun's launches. His truck really dipped out of the hole, and he said he was using the cheap summit shocks, so I decided to give them a try. These things are extremely squishy! They have my rear end all over the place on bumps in the road, though. I did a few launches with the street tires and let my friend check it out to see if it was squatting. With the toxics, the truck sat upright, with no squat whatsoever, therefore making the tires stay tall and firm. This created a great deal of tire spin. After the install of the summits, at launch on the street tires, the rear end dipped down alot, transfering more weight to the tires, and considerably reduced the tirespin. I have the street slicks mounted on stock tahoe wheels now, so I'm really anxious to try them out. I'm pretty sure I can hook this sucker now. So, in closing, I would recommend these shocks to anyone with a 3/4 drop or a 2/4 drop, and wants a good dip at the track. On the road, the shocks might be alittle too loose. My toxics kept me from bottoming out in alot of situations. Hope this might help someone out.

 

Man I'm getting a 2/4 put on and need some shocks. I live on some bumpy *** roads so which ones would you recommend? I love the look when I see a truck squat and take off.

 

Well, these summits will squat you quick! They are kinda loose on bumps. The toxics never bottom out, period. I'm going to run the toxics everyday, and the summits at the track.

 

I actually have his old shocks and drop now. They are definitely squishy. I just need his power to help it squat some more. Only problem now is one of them is blown. I guess its time for some new ones.

 

Whats the number on those shocks? Also do they have the same model shock for a stock height -2in shackle drop?

 

SUM-G7726- That is the part number for the ones I ordered. They don't list them for the new model Silverados, but I used the mounting sleeves off of my old shocks.



SUM-G7725- This is the number they give for a stock height.

 

Is there any concern for squatting too much so that the pinion angle/u bolts could be damaged?

 

I don't think it is squatting too much. Just enough to get a great weight transfer to the wheels. I'm not bottoming out anything, it just feels alot better out of the hole.
